Pine trees are coniferous evergreen trees that produce a commercially useful resin. Pine resin is a sticky liquid substance secreted from the bark of the pine tree capable of setting and hardening. Often referred to as pine pitch, pine tree resin is extracted and mixed with various ingredients to create useful substances.
Tar derived from pine resin is applied in veterinary medicine as an antiseptic, stimulant and diuretic. Tar oil is also used for the treatment of mange. Human medicinal use of pine resin is observed in American Indian tribes who value the resin for its anti-inflammatory properties. Pine resin treats rheumatism by reducing swelling and encouraging joint movement. It also acts as a natural remedy for abscesses, colds and coughs. The resin may be applied externally as an antibiotic and to treat burns and sores.
Rubbing oils and aromatherapy oils are said to strengthen and cleanse the body in alternative medicine. Holistic healers also use pine resin as a method to cleanse negative energy and promote strength by incorporating it into incense and fragrances. The tar produced by pine resin is used to create brown soaps, according to the Botanical website.
Rosin is a clear, brittle solid left over after pine resin is distilled into turpentine. Rosin is a common commercial additive in solders and fluxes, surface adhesives, synthetic rubbers, chewing gum and electronic insulating materials. Rosin is also used to make printing inks, detergents and paper sizing agents. Rosin is combined with other chemicals to produce salts and esters that are incorporated into these items.
Turpentine is a pine resin derivative used most frequently as an oil paint solvent and thinner. Isolated, distilled chemicals from turpentine contribute to the production of cleansing agents with a characteristic pine scent. Camphor, citronellol, linalool and menthol are other useful turpentine derivatives, according to the FAO Corporate Document Repository website.
